SPECIFICATION forming part of Letters Patent No. 588,123, dated August17, 1897.

Application filed February 15, 1897. Serial No. 623,571. (No model.)

To @ZZ whom, it may concern.-

Be it known that I, FRANK GEORGE BRU- BAKER, a citizen of the UnitedStates, residing at New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Car-Steps, ofwhich the following is a full and complete specification, such as willenable those skilled in the art to which it appertains to make and usethe same.

This invention relates to car-steps and thel object thereof is toprovide steps which are usually employed in connection with railwaycars,with a Ysupplemental adjustable step which is connected therewith andadapted to be lowered; and with this and other objects in view theinvention consists in the construction, combination, and arrangement ofparts hereinafter described and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof myimprovement are designated by the same numerals of reference ineach of the views, and in which- Figure l is a side view of a pair ofcar-steps of ordinary construction provided with my improvement, andFig. 2 a back view thereof.

In the drawings forming part of this specification I have shown a pairof ordinary carsteps, which consist of two downwardly and outwardlydirected side plates 5, and a plurality of stationary steps (5, whichare secured thereto, andin the practice ofv my invention I provide asupplemental bottom step 7 ,which is provided at its rear side withupwardlydirected arms S, whichare secured thereto in any desired mannerand which pass through keepers 9., secured to the lower two steps 6- and7, and connected with the upper ends of the arms 8 are chains or similardevices 10, each of which is connected with a crank 11, formed on a rody12, which is mounted in keepers 13 at the back of one of the uppersteps and. which is provided at one end with a spring-crank le, and thespring-crank arm la is provided with a rack-bar or lockingplate l5,which is secured to one of the sides (5.

The supplemental or bottom step 7 is also provided at its ends and nearthe front thereof with'rods or bars 16, which are secured thereto in anydesired manner and which pass through keepers 17 secured tothe sides 5of the steps, and these rods or bars 16 are each provided at its upperend with a cross-head 18.

The operation will be readily understood from the foregoing descriptionWhen taken in connection with the accompanying drawings and thefollowing statement thereof;

Whenever it is desired to lower the bottom step 7, the spring-crank arm14 is pulled ontwardly and disconnected from the rack-bar orlocking-plate 15, and said crank-arm is turned upwardly, and thisoperation turns down the crank 11, and the step 7 will at once drop intothe position shown in dotted lines in Fig. 1 and may be used as anordinary step, as will be readily understood, and when it is desired toraise said stepthe crank-arm 14 is turned down into the position shownin Fig. 2 and locked therein.

This device is'simple in construction and operation and perfectlyadapted to accomplish the result for which it is intended, and it willbe apparent that changes in and modifications of the construction hereindescribed may be made without departing from the spirit of my inventionor sacrificing its advantages.

Having fully described my invention, I claim as new and desire to secureby Letters Patent- The combination with a set ofcar-steps of asupplemental step connected with the bottom thereof, and adapted to belowered -and raised, said supplemental step being provided at the backthereof with arms or bars which extend upwardly through the keepersconnected with the main steps, and whichare provided at their uppervendswith chains, the other ends of which are connected with cranks formed onor secured to a horizontal rod, said horizontal rod being mounted inbearings on the rear side of the main steps and provided at one end witha spring-operated crank which is provided with a lock-bar orlocking-plate secured to the said steps, and said supplemental stepbeing also provided at each end with rods or bars which extend upwardlythrough keepers connected with the sides of the main car-steps,substantially as and for the purpose described.
